Upgrade from your small end caps on your stage 2 Z06 Spoiler to the more aggressive Stage 2/3 Wickerbill Rear Spoiler Wing Upgrade for C7 Corvette Z06. These end cap pieces are identical copies of the factory GM stage 3 pieces that are an option from the factory. You'll simply have to remove your existing smaller pieces and replace with these stage 3 unites. We include hardware to complete your "2 to 3" upgrade. Our Z06 upgrade winglets come pre-drilled, pre-painted in Carbon Flash Metallic and ready to install. Installation time is usually less than ten minutes.
